Gate valves consist of a valve body, a gate (or wedge), and an actuator. The gate moves up and down within the valve body, allowing or restricting fluid flow. When the gate is fully open, it allows fluid to pass through with minimal resistance, which is a key advantage of using gate valves over other valve types. Conversely, when closed, the gate completely obstructs the flow, providing a tight seal.

Applications of Saddle Clamps
Understanding their weight and load capacity is crucial for planning and executing infrastructure projects. ‘
The European norm EN 124 of 1994 applies to manhole and storm drain tops with a clear opening up to 1 m for areas subjected to pedestrian or vehicular traffic (covers with a clear opening over 1 m are specified in the British Standard BS9124 for example).[30] EN 124 specifies several weight classes depending on the application and is also being used in some countries outside the European Union. The lightest class A15 (cast iron) manhole cover can withstand a maximum weight of 1.5 tonnes. It would typically be restricted to light duty applications in pedestrian areas, gardens, patios, driveways and similar. By contrast, the heaviest class F900 manhole cover can withstand a maximum weight of 90 tons, making it suitable for docks, airports, and other extreme heavy-duty applications.[31]
